Jet 3 ultra needs new battery, where do you get them?

Question edited for clarity.

You have a dead short somewhere. You need some electrical knowledge and a digital multimeter for testing. Take all the covers off. Look for wiring that has rubbed through and touching or melted. Disconnect one of the motors and replace the fuse. If it still blows, reconnect that one and disconnect the other motor. If one motor doesn't blow and the other does, you know you have a faulty motor. If neither stop the issue, then you move up to the controller and look up there. With a meter you can check for shorts within the motors, as well as grounds.

Or just take it to a Service Centre and have it repaired and serviced properly.

vb any battery distributor or Interstate battery outlet should have the batteries you need you will need 2 U1 batteries and they will run 175.00 to 215.00 for 2. Do not buy auto batteries and the batteries need to be sealed deep cycle batteries. Do not get at Wal Mart or any other store that wants to sell you unsealed auto batteries Hope this helps you

you need to replace both batteries, their called U1 batteries (35 AMP-Hour)

one battery was low,,,,not sure if anyting else is bad, used chair...by having only one battery low, it ran down the chair...
